Upon encountering Pneumatit concrete, I had the unusual impression of both lightness and a simultaneous heaviness that does not burden but rather grounds. At the same time, a warming current rose from the soles of my feet up to my knees, and in the upper part of my chest (thymus gland), I experienced an expansion and opening. Overall, it was a strong and surprising sense of well-being. It was also impressive to transition from a floor made of conventional artificial stone to Pneumatit concrete. After just a few steps, I was astonished by the intense difference: On the artificial stone floor, there was a sensation of coldness, sterility, isolation, sluggishness and melancholy – while in the tractor hall with Pneumatit concrete came the described sense of well-being. In the 3rd basement level of Sativa’s new building extension, all these impressions were even more intense. It seemed to me that those who work here can energetically recover almost better than at home.
